Use a master passphrase instead of a password. Make it quite long, and personal, so that you won't forget it easily. The longer you make it, the more "obvious" (to yourself) can you make it sound, without compromising its security. Something like "It was a sunny afternoon the day I met my lovely puppy Rocket". Just use your own words, and the chances of anyone guessing it will be lower than those of brute forcing it. If you want to also have a shorter password for daily use, save it in a separate database protected with that long passphrase.
